Help with creating multiple xml files from an xml file with multiple tables

Hi,

If I have an xml file listed in part A. How do I create an xml file from data in each table as shown in part B using VB.NET?

Part A:

  <Root>
        <NSC>
              <ID> 1</ID>
                  <CTRY>BEL</CTRY>
              <NSC></NSC>
        </NSC>
        <NSN>
              <ID> 1</ID>
                  <CTRY>CAN</CTRY>
              <NSN></NSN>
        </NSN>
        <FIF>
              <ID> 3</ID>
                  <CTRY>CAN</CTRY>
              <FIF></FIF>
        </FIF>
  </Root>

Part B:

NSC.XML
<Root>
        <NSC>
              <ID> 1</ID>
                  <CTRY>BEL</CTRY>
              <NSC></NSC>
        </NSC>
</Root>

NSN.xml
<Root>
        <NSN>
              <ID> 1</ID>
                  <CTRY>CAN</CTRY>
              <NSN></NSN>
        </NSN>
</Root>

FIF.xml:
<Root>
        <FIF>
              <ID> 3</ID>
                  <CTRY>CAN</CTRY>
              <FIF></FIF>
        </FIF>
  </Root>



Thanks,

Victor

This should do it:
        Dim xmldoc As New XmlDocument, xmlout As XmlDocument
        xmldoc.Load("XMLFile1.xml")

        For Each xe As XmlElement In xmldoc.DocumentElement.ChildNodes
            xmlout = New XmlDocument
            xmlout.AppendChild(xmlout.CreateElement(xmldoc.DocumentElement.Name))
            xmlout.DocumentElement.AppendChild(xmlout.ImportNode(xe, True))
            xmlout.Save(xe.Name & ".xml")
        Next

Hi,

How do I save the xml files to a specific path? I need to save them to the  
"xmldoc.Load(Application.StartupPath + "\Data\LinkFiles\" folder.


  Dim xmldoc As New XmlDocument, xmlout As XmlDocument
        xmldoc.Load(Application.StartupPath + "\Data\LinkFiles\LinkFinal" & Me.username.Text & ".xml")

        For Each xe As XmlElement In xmldoc.DocumentElement.ChildNodes
            xmlout = New XmlDocument
            xmlout.AppendChild(xmlout.CreateElement(xmldoc.DocumentElement.Name))
            xmlout.DocumentElement.AppendChild(xmlout.ImportNode(xe, True))
            xmlout.Save(xe.Name & ".xml")
        Next

Thanks,

Victor

You can use the same logic for save as for load:
xmlout.Save(Application.StartupPath + "\Data\LinkFiles\" & xe.Name & ".xml")

Thanks for the quick solution, I am using the code below to rename one of the xml files but getting error message "could not complete operation because file already exist" how do you modify the code to overwrite existing LinkRowCountry.xml?

  Dim xmldoc As New XmlDocument, xmlout As XmlDocument
        xmldoc.Load(Application.StartupPath + "\Data\LinkFiles\LinkFinal" & Me.username.Text & ".xml")

        For Each xe As XmlElement In xmldoc.DocumentElement.ChildNodes
            xmlout = New XmlDocument
            xmlout.AppendChild(xmlout.CreateElement(xmldoc.DocumentElement.Name))
            xmlout.DocumentElement.AppendChild(xmlout.ImportNode(xe, True))
            xmlout.Save(Application.StartupPath + "\Data\LinkFiles\Link" & xe.Name & Me.username.Text & ".xml")
            My.Computer.FileSystem.RenameFile((Application.StartupPath + "\Data\LinkFiles\LinkPPF" & Trim(LoginForm1.username.Text) & ".xml"), ("LinkRow" & Trim(LoginForm1.username.Text) & ".xml"))
        Next

Open in new window



Thanks,

Probably simpler to save directly to the right filename depending on the value of xe.name:
xmlout.Save(Application.StartupPath + "\Data\LinkFiles\Link" & IIf(xe.Name = "PPF", "Row", xe.Name) & Me.username.text & ".xml")

Open in new window

But if you do want to rename the file after the save, first take it outside of the loop and then delete if target already exists (quick and dirty):
            If My.Computer.FileSystem.FileExists(Application.StartupPath + "\Data\LinkFiles\LinkRow" & Trim(LoginForm1.username.text) & ".xml") Then
                My.Computer.FileSystem.DeleteFile(Application.StartupPath + "\Data\LinkFiles\LinkRow" & Trim(LoginForm1.username.text) & ".xml")
            End If
            My.Computer.FileSystem.RenameFile((Application.StartupPath + "\Data\LinkFiles\LinkPPF" & Trim(LoginForm1.username.text) & ".xml"), ("LinkRow" & Trim(LoginForm1.username.text) & ".xml"))
